A permutation of an array of integers is an arrangement of its members into a sequence or linear order.For example, for arr = [1,2,3], the following are all the permutations of arr: [1,2,3], [1,3,2], [2, 1, 3], [2, 3, 1], [3,1,2], [3,2,1].The next permutation of an array of integers is the next lexicographically greater permutation of its integer. More formally, if all the permutations of the array are sorted in one container according to their lexicographical order, then the next permutation of that array is the permutation that follows it in the sorted container. If such arrangement is not possible, the array must be rearranged as the lowest possible order (i.e., sorted in ascending order).For example, the next permutation of arr = [1,2,3] is [1,3,2].Similarly, the next permutation of arr = [2,3,1] is [3,1,2].While the next permutation of arr = [3,2,1] is [1,2,3] because [3,2,1] does not have a lexicographical larger rearrangement.Given an array of integers nums, find the next permutation of nums.The replacement must be in place and use only constant extra memory. Example 1:Input: nums = [1,2,3]Output: [1,3,2]Example 2:Input: nums = [3,2,1]Output: [1,2,3]Example 3:Input: nums = [1,1,5]Output: [1,5,1] Constraints:1 <= nums.length <= 1000 <= nums[i] <= 100

Given an array nums of distinct integers, return all the possible permutations. You can return the answer in any order. Example 1:Input: nums = [1,2,3]Output: [[1,2,3],[1,3,2],[2,1,3],[2,3,1],[3,1,2],[3,2,1]]Example 2:Input: nums = [0,1]Output: [[0,1],[1,0]]Example 3:Input: nums = [1]Output: [[1]] Constraints:1 <= nums.length <= 6-10 <= nums[i] <= 10All the integers of nums are unique.

PermutationWrite a C function that takes an array of digits representing a number and returns a 2D array containing all possible permutations of the digits.For example, given the array [1, 2, 3], the function should return a 2D array containing the following permutations: [[1, 2, 3], [1, 3, 2], [2, 1, 3], [2, 3, 1], [3, 1, 2], [3, 2, 1]].Testcase:Input:1 2 3Output:1 2 3 1 3 2 2 1 3 2 3 1 3 2 1 3 1 2

Given an array nums of distinct integers, return all the possible permutations. You can return the answer in any order.

Assume we want to sort integers into ascending order. To sort a small array that contains 42, 17, selection sort will perform one swap, or three assignments. How many assignments will it perform to sort an array that contains these 10 elements: 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 ? Group of answer choices 15 18 24 27 63

Suppose an array of length n sorted in ascending order is rotated between 1 and n times. For example, the array nums = [0,1,2,4,5,6,7] might become:[4,5,6,7,0,1,2] if it was rotated 4 times.[0,1,2,4,5,6,7] if it was rotated 7 times.Notice that rotating an array [a[0], a[1], a[2], ..., a[n-1]] 1 time results in the array [a[n-1], a[0], a[1], a[2], ..., a[n-2]].Given the sorted rotated array nums of unique elements, return the minimum element of this array.You must write an algorithm that runs in O(log n) time.
